Pteroptyx surabayia View in CoL sp. nov.

( Figs. 101−112 View FIGURES 101-112 )

Type. Male. INDONESIA. 9 kms N Surabaya 7.vi.1972 I. Polunin ( ANIC) .

Paratypes (8). Same locality and collector as holotype, 4 males, 3 females ( ANIC). E Bali Gilimanuk 12.vi.1972, I. Polunin male ( ANIC) .

Diagnosis. One of three Pteroptyx species where males are without deflexed elytral apices and with an entire LO in V7; dorsally pale coloured; MFC with 4 strong teeth; PLP short and rounded and shorter than apically rounded MPP; LO in V7 not extending into MPP or PLP; female bursa with paired elongate plates which may be fused or not (difficulty in interpretation). Ballantyne & Lambkin (2013) scored this as ‘Pt sp MFC’ in their Figure 3 View FIGURES 3-10 .

Male. Colour ( Figs. 101 View FIGURES 101-112 ̄103): pale yellowish brown with dark tipped elytral apices; with paler white LOs in V6, 7 and dark brown head, antennae and tarsi; elytra appearing pale brown at base and narrowly along basal half of lateral margin; underlying hind wing may give impression that elytra are darker (wing should be pulled to side for examination Fig. 103 View FIGURES 101-112 ). Pronotum: subparallel-sided (B=C); all corners rounded obtuse. Elytron: apex not deflexed; apex of elytron not emarginate. Head: greatly exposed in front of pronotum; apical labial palpomere laterally compressed, longer than wide, with inner margin entire and less than half length of apical maxillary palpomere. Antennae: FS 1 longer than pedicel; no FS laterally produced. Legs ( Figs. 102, 108 View FIGURES 101-112 ): MFC with four strong teeth; no basitarsus emarginated. Abdomen ( Figs. 102, 104, 105 View FIGURES 101-112 ): posterior margin of V4 sometimes recurved; LO in V7 entire reaching sides, and into anterior portion of MPP; PLP short apically rounded, shorter than apically rounded MPP. T8 ( Fig. 105 View FIGURES 101-112 ): without flanges; posterior margin trisinuate with median emargination short and narrow. Aedeagus ( Figs. 110 View FIGURES 101-112 ̄112): approximately 4 X as long as wide; LL separated by half their length, narrowed and obliquely inclined at their apices, with anterior margin rounded; b/a 0.8.

Female. ( Figs. 106, 107 View FIGURES 101-112 ; associated by label data only). Coloured as for male except for pale LO in V6 only. Bursa plates ( Fig. 107 View FIGURES 101-112 ) appearing as two broad elongate plates on each side; anterior plates curved; posterior plates inclined transversely to anterior plates and subtriangular in outline, may be attached to anterior plates but interpretation is unclear; posterior plates approach very closely at their inner margins and may be joined there also.

Etymology. The species is named for its type locality, surabaya being considered a noun in apposition.

Comments. The placement of this species in Pteroptyx is tentative only.
